 * Hi [@hcbcwebster](https://wordpress.org/support/users/hcbcwebster/), this is 
   Nik from 10Web, thank you for reaching out!
 * I noticed that the page you mentioned seems to no longer exist, so I’m unable
   to check the gallery directly. Could you please share a link to a page where 
   the Form Maker form is currently embedded to? Additionally, could you please 
   specify the version of the Form Maker plugin installed on your site at the moment
   of encountering this issue. That will help me look into the issue more precisely.
 * In the meantime, have you tried testing for a possible theme or plugin conflict?
   You can do this using the [**Health Check & Troubleshooting** ](https://wordpress.org/plugins/health-check/)
   plugin. It allows you to temporarily disable themes and plugins only for your
   logged-in session, without affecting what site visitors see. This way, you can
   safely check whether the Photo Gallery plugin works properly with the default
   theme and no other plugins enabled.
 * Once you share the working link, I’ll be glad to assist further!
